Correct, Bilstein does have a direct replacement available for the JK. At 0-inch it is the HD.
However, if you want the 5100, it is considered a 1.5-3-inch shock. If you run that shock at stock ride height, there tends to be some complications. One issue is that there is enough droop to pull the spring out, so a spacer is required. Also, it is recommended to use a different offset wheel with the 5100 because the sway bar end link will run the tire. Also, you might have to adjust bumpstop height.
But other than that...
